[Asterisk-Users] Re: Adtran 750 DID question.

[Bisker, Scott (7805)]

I guess asterisk is winking properly then, because the line rings when dialed.  In zaptel.conf the lines are set to e&m and in zapata.conf they are set to e&m_w.  The FXS cards are series L1.  

 What I'm seeing is that the DNIS info is not being passed through to asterisk.  Since I get no DNIS, it shoves the call to my s extension.

This is what I see on console

    -- Starting simple switch on 'Zap/3-1'

Once I see the call come in I do a show channel and here is what I get.

 -- General --
           Name: Zap/3-1

Any ideas on this?

When some one calls into your DID Trunk line what symptom do you see on
Adtran as well as on Asterisks console? 

Asterisk winks properly in FXO DPO mode, we had checked this things with our
Telco instruments. If your PBX doesn't wink to Telco, your DID line's will
become busy, that is one way to check whether Asterisk is winking properly
or not.

What series FXS card you are using? Is it L1 or L2? Because only L1 series
cards work with our DID trunk line. I don't know why and still Adtran
technical support is not able to figure out. 

I have same configuration running in my office and finally with all the help
from Digium and adtran, problem seems to be less. 
Still fully it is not resolved yet because FXS L2 is not working. 

Hopefully Adtran will release new firmware.

I had similar problem and it took all most 2 months to resolve it.

Few things you have check in your Adtran 750 configuration. 
1. For incoming DID trunk line it has to terminated on FXS card. (Which I
think you already did)
2. FXS card needs to be set on FXS DPO mode in order to work properly.
3. Your DID trunk line should be configured in Asterisk as "em" in
zaptel.conf and e&m_w in Zapata.conf.

Reason you are facing this problem either your battery is not getting
reversed and Telco can't see Answer Supervision on your line when the calls
get connected. If you have ohms meter or multimeter check your DID line
voltages. When inbound call comes in and both parties go off hook you should
see positive voltage on that line, in idle situation(on hook) you will
negative 48V.

Yes, local calls are different then long distance. Answer Supervision is not
required for local calls. Only for long distance it is required, so that
Telco can start billing.

Hope this should resolve your problem.

I have an updated question on this one.  It seems that only inbound long =
distance calls (calls from outside the local calling area) on our DID =
trunk have one-way voice.   I have my adtran 750 fxs lines configured as =
FXS Loopstart with all the defaults.  Again, the problem is that once = the
call bridges, the outside caller can hear the person they called, = but the
inside person can't hear the caller.  This happens regardless of = the
internal technology, SIP, Zap, H323.

Could it be possible that inbound long distance calls are signalled =
different than inbound local calls?  Inbound calls on the PRI work =
flawlessly.

Any ideas
